Original scientific paper In the design of roads, embankments stand out as the most sensitive elements of design in terms of cost-effectiveness, safety and comfort, and are influenced by numerous factors: subsoil fill, embankment material, groundwater level, proximity of earthquake faults, etc. Cost-effectiveness on the one hand, and safety and comfort on the other, are always in conflict. A solution should therefore be sought to somehow satisfy all the demands placed during the design stage. The subject of this paper is to find the best (optimal) solution in the design of embankments. Criteria for the design of road embankments have been analysed and optimized. The results of embankment design optimization are shown taking into account criteria for determining the optimal solution (economic criteria, safety criteria, traffic criteria, geological and hydro-geological criteria). Research results are presented analytically and graphically.

Primjena metoda višekriterijske optimizacije kod projektiranja nasipa prometnicaIzvorni znanstveni članak Tokom projektiranja saobraćajnica, izdvajaju se nasipi kao najosjetljiviji dio sa aspekta obezbjeđivanja ekonomičnosti, sigurnosti i udobnosti, a na to utiču mnogi faktori: temeljno tlo nasipa, materijal od kojega se gradi nasip, visina podzemne vode, blizina rasjeda pri zemljotresu i dr. Ekonomičnost s jedne strane, i sigurnost i udobnost s druge strane, uvijek su u koliziji. Zbog toga je potrebno tražiti rješenje koje će na neki način zadovoljiti sve zahtjeve koji se postavljaju tokom projektiranja. Predmet istraživanja ovog članka je iznalaženje najboljeg (optimalnog) rješenja tokom projektiranja nasipa. Analizirani su kriteriji projektiranja nasipa prometnica i izvršena je njihova optimizacija. Prikazani su rezultati optimizacije nasipa, uzimajući u obzir kriterije za određivanje optimalnog rješenja (ekonomski kriteriji, kriteriji sigurnosti, prometni kriteriji, geološki te hidrogeološki kriteriji). Rezultati istraživanja su prikazani analitički i grafički.
